Is there a way to bulk approve/deny emails that get caught in Office 365 transport rules and go to moderation to approve or deny? Currently I am approving emails individually which is teadious so looking for a quicker way to do this.

So are you approving all emails blindly? Sounds like you just need to turn moderation off altogether?

Report back so we can hash this out.

No we have rules setup in exchange online that if emails contain inappropriate words (we don't want students bullying and swearing at each other through the college email) they get sent to moderation as well as mail that could be potentially spam.

At the moment we are getting a bit of spam so I simply mass delete these rather than decline them and at other times we get emails that contain inappropriate words but need to be allowed through as they may relate to child welfare issues. An example would be that a parent information night might contain information about how to talk to your children about sex so this gets flagged and goes to moderation. As this goes to many parents we currently have to approve each email one by one which is time consuming. What we want to be able to do is select all of these and just hit approve and have the whole selected list get approved at once rather than doing each one by itself.

Honestly this is exactly what moderation is for and it seems to be setup correctly from reading your detail.

Unless these emails that need to be bulk approved have some consistent pattern you will not be able to set an exclusion in the DLP rule to skip them or setup a new rule above this one to catch these into a separate bucket...

No pattern, the emails are randomly sent throughout the year and all contain different subject matter. I am guessing by your response that it is simply not possible to highlight a number of emails at once and press approve.
